Answer:
The measure of angle 2 is 38 degrees
Step-by-step explanation:
38 degrees and angle 6 are vertical angles and are equivalent. Angle 6 and 2 are alternate interior angles meaning that they are also equivalent. So the angle of measure 2 must be 38 degrees.
It would be 27/30 and 28/30
He can go 8 times 1040-800=240/30=8
Step-by-step explanation:
Basically 15x<30 is saying that 15x is less that 30. So that means x can be any number as long as when multiplied to 15 it has to be less then 30. So they only number available is 1. So 15(1)<30. Im not sure what the question is but X=1
Answer:
a : b = 25 : 9
Step-by-step explanation:
(3a - 5b) : (3a + 5b) = 1 : 4
Product of extremes = product of means
(3a - 5b) *4 = (3a +5b) * 1 {Distributive property}
3a * 4 - 5b*4 = 3a + 5b
12a - 20b = 3a + 5b
Add 20b to both sides
12a = 3a + 5b + 20b
12a = 3a + 25b
Subtract 3a from both sides
12a - 3a = 25b
9a = 25b
a:b = 25 : 9
